LABORATORY EVALUATION OF ELECTRIC ARC FURNACE SLAG AS A POTENTIAL WETLAND SUBSTRATE By Harjinder Kumar

ii This research work is being dedicated to my grandmother the late Amar Kaur. Her authoritative figure has always been the beacon and source of inspiration for me to strive and excel in my life. iii Phosphorus (P) is considered as the controlling element in the proliferation of eutrophication in water bodies. Constructed wetlands are accepted as the most appropriate treatment technology for removal of nutrients, including phosphorus from agricultural drainage waters. As most of P removal in constructed wetlands is through precipitation and abiotic sorption, introduction of suitable substrate can enhance the P removal efficiency of the system. Slag has immense capacity for P sorption however its composition and ability as a wetland substrate varies from locale to locale
